22 claims. l

This invention relates to a machine for making sandwiches such as peanut butter sandwiches and the like by providing means for feeding a cracker or cake along pre-determined paths, depositing a ller onto the cracker or cake, then depositing another cracker or cake on top Vof the first named cracker or cake in such a manner that the two crackers or cakes are in perfect superposed relation and then delivering the nished product from the discharge end of the machine to a suitable conveying means where they are usually packed into packages containing several of the nished double-decked crackers or cakes with the filler therein.

It is an object of this invention to provide a machine for making confections such as peanut butter sandwiches and the like by providing a plurality of conveying means disposed in side by side relation and having a magazine for holding a plurality of stacks of crackers or cakes, there being one magazine for each conveyor, whereby there may be provided a lling feeding mechanism having outlets for each of these conveyors for depositing in timed relation a pre-determined amount of lling material onto the cracker or cake which has been released onto the conveyors, and providing additional magazines for crackers or cakes and releasing a second cracker or cake onto the top of the first cracker or cake having the lling thereon at a pre-determined time to cause it to be superposed on top of the first cracker or cake with the filling material therein.

Means are also provided whereby if the production of the machine is greater than can be handled by the wrapping department to which the finished superposed crackers and cakes are delivered, for cutting out one or more of the feeding means for the crackers and for the lling material to thereby reduce the combined output of the machine until such time as the packing department has caught up with the output of the machine.

More specifically, it is another object of this invention to provide a sandwich making machine of the character described wherein the conveyor has one or more longitudinal rows of spaced pockets thereon with a pair of vertically movable pins associated with each of said pockets. Each of the cake feeding stations or magazines hasV a slotted platform thereon disposed immediately above the conveyor extending longitudinally of the conveyor and onto which the crackers or cakes are deposited, one at a time, in timed relation to movement of the conveyor.

A cam means is provided for elevating the pins as they move Past each of the magazines to thus cause the upper portions of these pins to pass between the slots in the corresponding slotted platforms for removing each successive cracker or cake therefrom and directing the same onto the, corresponding pocket or pockets, the cam means being so arranged as to permit the pinsto assume a lower position, relative to the position they assume while passing adjacent the magazines, as they pass beneath the filling feeding mechanism so that the filling feeding mechanisml mayfloe'` disposed closely adjacent the upper surfacesy of the crackers or cakesV on the pockets as the Iillir'ig is dispensed from the filling feeding mechanisml onto each successive cracker or cake from the rst of the magazines. Y Some of the objects of the invention 'having been stated, other objects will appear as the de` scription proceeds, when taken in connection w.' hf the accompanying drawings, in which- Figure 1 is a side elevation of a sandwich ma chine with parts omitted and other partsbeing broken away, showing the improved magazines and the arrangement thereof and showing a lling' dispensing apparatus disposed therebetween,4 schematically;

Figure 18 is-an isometric view of the framework of the machine omitting all parts that fare not integrally welded to the .framework of the machine.

Referring more specifically tothe drawings, the numeral I0 indicates alower'longitudinal .frame bar while II indicates a similar .bar on the other side of the machine (Figure 18). At one end these bars I0 and I I are joined togetherby an end bar I2 and at the other end the bars VI0 and respectively have Adownwardly projecting bars .I3 and I4 (Figures 2 and 18) to the lower ends of which is secured a `transverse end bar I5. At the discharge end of the machine the lower frame is supported by vertically disposedlegs I6 and I1.

Near the intake endof the machine are vertically `disposed legs 20 and 2| which vare joined together by a transverse bar 22. Also there .are downwardly projecting bars 24 and 25 extending downwardly from the side bars |0 and I I respectively -to which is secured a transverse bar 26. The bars I5, 22 and 26 support a plate member 21.

The bar |0 has rising upwardly therefrom uprights 30 and 3| whose upper ends are connected to-anupper horizontal-bar 32. The bars 30 and 3| are bridged by a bar 33 and extending from bar 30 is a bar 34 which has an upright bar .35 which vis connected to one endof the horizontal frame bar 32.

The lower horizontal bar I Ihas rising upwardly therefrom uprights 36 and 31 which yare similar to bars 30 and 3|. These haveextending therebetween a bar `40 and the upper ends of the bars 36 and 31 are secured to an upper horizontalbar 4|. Extending toward the discharge .end of the machine and secured to upright bar 36 isa horizontal intermediate bar 42 which hasan upright bar 43 securedtheretoand which isalso secured to the upper horizontal bar 4 I.

Both the upright bars 30 and 36 have secured theretoone end of horizontal bars 44 and 45 respectively which project toward the intake end of the machine and have secured on the uppersurfaces thereof, near their free ends, uprising pins 46 and 41 which have xed thereon a transverse bar 50 which bridges the gap between the free ends of the bars44 and 45.

The bars 3| and 31 have secured thereto one end of bars 52 and 53 whose free ends have secured therebetween a shaft 54. Secured to and rising upwardly from the upper horizontal bars 32 and 4| are upright pins 55 and 56 to the upper ends of which is secured a transverse upper bar 51.

The upper horizontal bars 32 and 4| have, near the discharge end, and intermediate the ends, of the machine, downwardly projecting portions 64 and 65 to the lower ends of which are secured transverse bars 65.

Secured to the proximate surfaces of intermediate horizontal bars 33 and 40 are bars 10 and 1| (Figures 5 and 18). Secured to the ends of the upper horizontal bars 32 and 4| and spanning the distance therebetween is an angle bar 14. To the rear surface of angle bar 14 is secured a transverse bar 11.

The ,upper horizontal bars 32 and 4| are connected at the intake end of the machine by a transverse bar 80. Disposed on the proximate sides of upper horizontal bars 32 and 4I are the projections 8| and 82 (Figures 5 and 18) which serve .to support the upper reach of the conveyor chains while the ,bars 10 and 1| support the lower reach of the `conveyor chains as will be later described.

Mounted on the plate 21 is an electric motor 00 having wires 9| and 92 leading from a suitable source of current, not shown, into the motor (Figures 1 and 2). This motor has a V-pulley 93 on its motor shaft 94 on which is mounted a V-belt 95. VThis V-belt 95 is mounted on a V- pulley 96 on one side of a variable speed drive mechanism 91, this comprising the input side of the conventional variable speed mechanism. The drive ,mechanism 91 has van output shaft |02 whichhas a pulley |03 fixed thereon on which a V-belt |04 is mounted. said V-belt |04 being mounted on a pulley |05 fixed on a shaft |06 rotatably mounted in bearings |01, which are mounted on the lower horizontally disposed bars I0 and Shaft [0:6 has mounted thereon a V-pulley IIS which has mounted thereona V-belt I I which is also mounted on a larger V-pulley I2 secured on a shaft ||3 mounted for rotation in bearings II4 disposed on the intermediate horizontal bars 33 and 40. Adjacent the pulley ||2 is a sprocket wheel I I6. There is mounted in suitable bearings ||1 on horizontal bars 44 and .45, a shaft ||8, which has xedly mounted thereon sprocket Wheels |20 and |2|.

Rotatably mounted in bearings |25 disposed on the horizontal bars 52 and 53 is a transverse shaft |26 on which is fixed a sprocket wheel |21. Rotatably mounted on a suitable stud shaft |28 is an idler sprocket |30. The stud shaft |28 is fixed to the vertically disposed bar 31.

Mounted on the sprocket wheels IIB, |2I, |24, |21 and idler sprocket |30 is a sprocket chain I3 I. This imparts rotation to the shaft 8, which, as has already been described (see Figure 3), has fixed thereon the sprocket wheel |20. Sprocket Wheel |20 has mounted thereon a sprocket chain |32. Sprocket chain |32 is also mounted on a largersprocket wheel |34 xed'on a transversely disposed shaft |35 rotatably mounted in bearings |36 disposed on the lower side of the upper horizontal bars 32 and 4|.

Mounted on the transverse shaft |35 aretwo sprocketwheels |40 and |4| (Figures 1 and 5) on which endless sprocket chains |42 and |43 are mounted. Every fourth link of these chains has outturned lips |44 and |45 to which transverse bars |46 are secured by means of suitable bolts |41 (Figure 5). The sprocket chains |42 and |43 of the main conveyor near the intake end of the machine are also mounted on sprocket wheels 50 and |5| respectively (Figures 1 and 2) secured on a transverse shaft" |52 which is mountedfor rotation in bearings |53 secured to the lower sides of upper horizontal bars 32 and 4|. f' v The upper layer or reach of the conveyor, of which sprocket chains |42 and |43 are parts, is supported by the guide bars 8| and 82, whichV are integral withthe proximate sides ofthe upper horizontal bars 32 and 4|. The lower layeror reach of this conveyorof whichV sprocket chains |42Y and |43 are main parts, is supported by the guide bars 10 and 1| which are integral with the proximate sides f intermediate horizontal bars 33 and 40, as well as horizontal bars 34 and 42 (Figure The ends of the transverse bars |46 have wear shoes |54 and |55 secured thereon which contact thesupporting bars 8| and 82 to support the upper leaf of the conveyor while it is traveling from theintake end to the discharge -end vof the machine. Each of the transverse bars |46 has a plurality of cracker receiving shoes or pockets |56 xedly secured thereon in spaced relation to each other and all of these cracker receiving shoes are spaced at the same position along all of the transverse bars |46 so as to provide aligned rowsof .cracker receiving shoes throughout the entire'length of the conveyor of which chains |42 and |43 form a part.

These cracker or cake receiving shoes |56 have spaced side walls |60 and |6| and a bottom portion |62 (Figure 12). These side walls |60 and |6| of the cracker supporting shoes |56 are spaced closer to each other than the width of the cracker so that the crackers indicated by reference character C are supported on the top edges of the portions |6| and |60. The partial bottom of the cracker or cake shoes and which has been described by reference character |62 has a downturned lip which is welded to the transverse bar |46. Y f'I'he outermost cake supporting members |56 on each side of the main conveyor have welded tothe inside surface of the outer uprising portion |6| thereof, on one side of the conveyor, and |60 on the other side of the conveyor (Figures 5, '1, 15, 16 and 17), a plate member |64 which projects rearwardly of the rear end of the cracker supporting members |56 and has a vertically disposed hole therein whichis slidably penetrated by the endmost pins |65 of bars |66 in which these pins |65 are mounted.

The bars |66 have welded near each end thereof U-shaped members |61 and |68 which are adapted, near the discharge end of the machine, to ride on trackways |10 and |1|.

The supporting bars |10 and |1| are supported atV their ends by spacer collars |12 and 13 which in turn are supported by bars |14 and |15 which are supported near one of their ends, and inter-I mediate their ends, by the transverse bars 66 and at their opposite ends Iby another transverse bar 69 secured between the uprights 3| and 31 (Figures 1, 2, 5, '1 and 18) The spacers |12 and |13 are of varying height and are of such height as to vary the level of the U-shaped members |61 and |68 progressively as they move from the intake end to the ldischarge end of the machine. It will be noted, for example in Figure 6, that these bars have at their beginning near the intake end of the machine no spacer collars V|61 and |68 thereunder. These bars |10 and |1| are held in position by meansv of suitable stove bolts |16 penetrating both bars |10 and `|1| and thesupporting bars |14 and |15 '.hich vare supported by the transverse bars 66 and-69.

The-bars, |66 have at each end vthereof pins |80 and" |8| projecting in an opposite direction therefro'mfto the4 pins |65 (Figures 5, 7,15, 16 andgl'lli These 'pinsl80 and |8| slidably-penetrate 'a hole in the en'd ofplate members |82 and |83', secured at theirotherends yto the transverse bars'l46ff1n this manner, Ithe bars |66-,are mounted for`sliding `movement relative to the barsy |46 and the plates |82 and |83 which are welded to the bars |46. j

'I'wok different spaced dispensing stations are provided for feeding the crackers or cakes into the conveyor, and these stationsare identical and like reference characters will apply except' that the 'first feeding means which is not shown in as full detail as the'se'cond feeding means will have prime' notations added to like parts, and a thorough description will be'given ofthe second feeding means which is shown inmore'detaillFigures 1. 2. 3. 4.18, 9, 1oand13).

The crackeror cake magazines each comprise auplater 280 having angle strips 20| near their outer edges 'to which are 'secured they sidewalls 202 and 203, respectively` and also fixed to the plate 08 are'walls 204,285, 206; 201, 208, 289', 2|0 ,and` 2||, thus providing chutes or supporting areas indicated by reference characters 2I5, ,2|6,

`2|1, '2|8, and 2|9, for stacks rof crackers. u

The side walls 202 to 2|| project inwardly toward each other to narrow the chutes 2|5 to ZIB inclusive near the bottom thereof to give a sufcient clearance for travelv ofthe crackers while the top portions of these chutes are broader to make feeding of crackers thereinto all in a stacked form more easily accomplished. 'I'he members 20| to 2|| inclusive have inturned lips 222 which restrict the open side of the chutes 2|5 to 2|9 near their lower ends to prevent the crackers from jarring forwardly out of the chutes as vthese',lipsrestrict the passageway to a width which is narrower than the width ofthe crackers.

The members 204 to 2|| inclusive are secured in position by means of a plurality of blocks 223 (Figure 4) being secured between pairs of the same by means` of a screw 224 penetrating the sheetmetal member 200 and then suitable rivets or screws 225 penetrate the members 204 to 2|| inclusive and in the case of rivets, would penetrate the blocks 223, and in the case 0f screws would be threadably imbedded inthe block 223 to therefore hold the members 204 to 2|| inclusive in assembled position.

The side members 202- and 203 are secured to the angle members r20| as by screws 226 penetrating the angle members .and being threadably imbedded in the side members 202 and 203.. The angle rnembers`20| are suitablysecured to the sheet metalplate '200 by means of suitable screws 221.

vThevcrackers or cakes are fed into the top or broaderportions of the chutes 2 5 to 2 9 inclusive to provide an elongated stack of .thecrackers in each c hute and then an attendant will continue to feed additional crackers into these chutes to cause an ample supply to be in the chutes at all times.

The lower edge of plate 200 has secured thereto by any suitable means an angle bar 230 which has welded thereto a cross bar 23| whose ends are supported in` uprights I232 and 233 (Figures 8and 9). The `shaft 23|l is rounded lat its ends and lis oscillatably mountedv in the uprights 232 7 and 233 and has nuts 234 and 235 on its outer ends, by means of which the lshaft 23| can be adjustably clamped in position when the angularity of the metal plate 200 is determined. The

angularity of this metal plate may be adjusted by means of square shaft 236 being secured to the lower side of the plate 200 which shaft is rounded at itsends and penetrates blocks 231 and 238 and nuts 24| and 242 are threadably mounted on the outer ends of the rod 236 to secure the blocks 231 and 238 in position (Figures 1, 2 and 3).

Fixed in the lower ends of blocks 231 and 238 are rods 243 and 244 which are threaded at their lower ends and penetrate top horizontal side bars 32 and I4I and have nuts 245 and 246 disposed above and below the bars 32 and 4I for adjusting the vertical position of the rods 243 and 27744.

Secured on their lower .ends to the forward lower surface of the angle bar 230 near the end of said angle bar 230 by means of suitable screws 250 are side upright bars and- 2'52 (Figures 8, 9 and 10) Secured at its ends to the posts 25| and 252 by means of bolts 253 and 254 is a plate 255 which extends across the machine. Secured to the upper surface of plate 255 is a bar 256 by means of bolts 253 and 254 and this bar 256 has a plurality of upwardly and rearwardly projecting lips 251 which overlie the lower ends of the chutes 2I5 to 2 I9 (Figures 8 and 9). These projections 251 are for preventing upward movement of the lowermost crackers during a feeding operation.

The plate 255 has raised portions 260 (Figures 9 and 10) spaced apart from each other. These raised portions 260 are on the lower side 0f plate 255 and in the spaces between these raised portions suitable gates 262 are mounted for sliding movement. These gates have a reversely bent portion 262a adapted to slide on the upper side of plate 255.

Secured to the plate 255 by means of suitable screws 263 is a transverse bar 264 which has spacer washers 265 (Figure 8) at various points along the bar-to hold the bar 26.4 in spaced relation to the plate 255. The upper leg 262a projectsA downwardly between the plate 255 and the bar 264 and has an outwardly and upwardly turned leg 262D which limits upward movement of the gate 262 (Figure 8). The bar 264 has a. bore 266 associated with each portion 262a in which is mounted a ball 261 which is normally urged against the leg 262a by means of a compressionspring 268.

There is a flat strip 210 secured on the top surface of bar 264 by means of the same Screws l263 which secure the bar 26,4 to the plate, 255 and -this flat barV 210 confines the compression springs 268 inY position to push' the ball 261 against the surface portion 262a so as to hold the gate 262 in elevated position when it is raised to the position shown in Figure 8, since the leg 26211 has a der iressiony 21| near its lower end which, is adapted -to be entered by the ball 261 to hold the gate Y262 in elevated position. The gate v262 when in lowered position is adapted to close the lower end of the chutes 2|5 to 2|9 inclusive to prevent a cracker from falling downwardly to where it can be expelled from the chute.

Secured to the lower surface vof the angle bar 230 is a plurality of spaced cracker receiving and supporting members or platforms broadly referred to by reference character 215 (Figures 8, 9 and 10) This member 215 has a leg 216 which is secured to the lower surface vof `angle bar 23|)l by means of suitable screws 211. The leg- 216 has integral therewith a downwardly and forwardly projecting platform portion or ledge 218.

The portion 216, as is clearly visible in Figures 8 and 10, has integral therewith side walls 262 and 283 which have inturned flanges or spaced supporting members 284 and 285 at their lower edges which provide a space therebetween of less dimensions than the width of a cracker. These spaced supporting members 284 and 285 project substantially beyond the ends of the side walls 283 and 282. The downturned portion 218 has a pair of gaps 286 and 281 cut in the lower edges thereof through which the pins |65 pass to remove a cracker from the inturned portions or ledges 284 and 285 and to carry the cracker along to the free ends of these inturned portions or ledges 284 and 285 to where it will fall by gravity .onto the conveyor chain in the first cracker dispensing assembly whereas ln the second conveying assembly the cracker will fall onto the filling which will have been deposited onto the first cracker.

There is provided a plate 290 (Figures 8 and 10) which is turned at right angles at its upper ends as at 29| and to the upper side of this plate 290 and to its portion 29| is secured, by means to be presently described, a closure plate 292. It will be noted in Figure 8 that the plate 292 terminates a substantial distance short of the'lower edge of the plate 290 thus forming a leaf portion or member projecting below the closure plate 292. The sheet metal plate 290 projects at each end beyond the ends of plate 292 and these ends are slidably mounted in grooves 293 and 294 in the angularly disposed posts 25| and 252. The lower surface of plate 290 is reinforced by meansof a bar 295 which is secured to the plate 290 and to the plate 292 by means of bolts 296 penetrating the above named parts.

Secured to the outer surface of this plate 290 and near the top portion thereof by any suitable means such as bolts 300 penetrating plates 290 and 292, is an angle bar 30| which is also penetrated by the bolts 300. At each end of angle bar 30| suitable bolts 303 penetrate the forwardly projecting leg of angle bar 30| and the lower` portion of these bolts 303 are penetrated by pivot pins 355. These pivot pins 305 pivotally support the upper ends of connecting rods 306 whose lower ends are pivotally connected by pivot pins 301 (Figure 8) to forked bolts 3|0 which penetrate a bar 3|| and these bolts are confined in position by means of nuts 3|2 on the lower end thereof.

The shaft 3| I near its ends has abutting thereagainst the upper ends of inclined levers V3I3 and 3I4 (Figures l, 2, 9 and 10) which project downwardly and forwardly and are xed to the two ends of a shaft 3I5 mounted in suitable bearing blocks 3I6 disposed on the horizontal intermediate bars 34 and 42. It is to be noted that the bearing blocks 3I6 are mounted on similar intei-mediate horizontal bars 33 and .40.

The bar 3|| is rounded on its right-hand end in Figure 10 or the end nearest the observer in Figure l and has pivotally mounted thereon a connecting rod 3|1 which has its lower end eccentrically connected to an eccentric wheel 320 which isdxed on the shaft I I8 mounted in bearing blocks I1. The structure for the first cracker dispensing means is identical to the second means except that the connecting rod 3|1' is connected to an eccentric wheel 325 which, in-

stead er being mounted Aon shaft ns, is mounted .lip 326l which has a vertically disposed hole there-` through which is penetrated by a shoulder screw 321 and allows vertical lsliding movement of the tionl to bar 51.

The lower portion of each member 325 has a horizontally disposed portionv 328-. This has a pair of grooves 330 and 33| in its lower surface through which the' pins |65 may pass if no i# cracker is' present tohold the member 325 in elevated position'and thus this arrangement prevents thepins |65 from having to raise the member 325 in the event no cracker is'in position to h olda member 325 in elevated position (Figure "F1 8). The purpose of the member 325 is to cause the lower horizontal portion 328 to engage the crackers as they travel through the machine and, as will be observed in Figure 8, it will hold the crackers C-2 in horizontal position until they arel entirely removed from the inturned flanges 284 Aand 285 so that the cracker will fall in a horizontal attitude onto lthe filling F deposited onto the previously deposited cracker C-I.` .filso mounted on the shaft |06 is a' V-pulley 350, (Figure 2) which has mounted thereon a V-belt 35|'which is also mounted on a pulley 352 xedlyzsecured on a shaft 353. Theshaft 353 is supported by bearings 354 at the ends thereof which are secured on the lower surfaces of frame members |70 and k|V A(Ifiguresl and 2). Y The end of the shaft 353 remote-, from the observer in Figure 2, but nearest th observer in ,Fi'gureL` has arsprocket wheel 3641mounted thereon on which is mounted a sprocket chain 365 which is also mounted on a sprocket wheel 366 fixedlymmounted on a shaft 358.

The filling feeding apparatus may be of any desiredconstruction `provided that it operatesVV to .dispense fillingl material at predetermined intervals in timed relation to movement of the conveyor. Thus. the driving means for the lling feeding apparatus is shown in detail, but the filling feeding apparatus is shown schematically and indicated generally at 315. The apparatus 315 does not, necessarily, constitute a part of the present invention andQther'efore, a detailed description thereof is deemed unnecessary. This apparatus 315 may be of the type disclosed in my co-pending application entitled DispensingI Apparatus for ViscousdMaterial andv Method." SeriahNo. 251,725, filed October 17, 1951.

In this instance, the -illing feeding apparatus |56 of the conveyor by means of fourv spacer blocks 316, there being two on top of each' of the bars 32v and 11|.Y Resting on top of these blocks is a plate member 311 and the plate member 311.

kzo 315 is supported in spaced relation to the pockets Vtical to each. other.

10. as well Vas the spacer blocks 316 are penetrated by screws 380 which are threadably imbedded inthe horizontal bars 32 and 4|. This plate 311 is the base portion vof the filling feedingapparatus 315.

One great advantage of vhaving the cake holding chutes at an incliney such as shown in the drawings, is that -the-vplate 200 supports thev greater portion of the weight of the column vof cakes and therefore the reciprocating member 292 in removing the lowermost cake will not grind the uppersurface thereof or sometimes break the lowermost cake lbecause there will not benearly as muchl-pressurelexerted on the lower-- mostcake asftherefwouldbe ifl the chutes-were Vert-[11034],"A

Mounted ron suitable :uprisers 590 rising from upper-horizontalbars32 and 4| vis a transverse bar-1592 (Figuresn 1, 2, 14, 15 and 16) which has vertically disposed holes therein in which` are oscillatably mounted bolts 593 and 594. The lower ends of these bolts 593 and 594 are slotted longitudinally of the machine and have a pivot pin 595` therein .on which are `mounted'oneY end ofy bars 596 and 591. The bars'596 and 591 project forwardly in closeproximity to the discharge orices of the filling feeding means 315.

Also mounted on suitable uprisers 600 and 60| is a transversebar 6021 which has pivoted'as at 603 and 604 bell crank levers v-605and 606 whose short legs abut each other and have semi-circular vcavities therein which `are penetrated by a pin 601 which is dropped down througha lsuit-f able hole 608 in the bar 602 and serves as'a roller bearingbetween the short legs of the bell crank members 605 and 606.v

' The bell cranklmembers605 and 606 have their free long legs'normallybiased andmoved toward each other by means of ya tension spring 6|0. f The hole 608 is normallycovered bya cap member 6| I. Near the free ends of the bell cranks 605 and 606'fis pivotedV a link member 6|4 as at 61|1. Thelfree ends of bell cranks 605 and 606 havedownwardly projecting pins 6|2` and 6|3. Loosely mounted on the lower ends of pins 6|2 andf6|3 which are headed, are the members 6|5 and 6|6 which have horizontal upwardly projecting legs which project toward Veach other and then an upright ,portion and then an upper horizontal portion designated at 6|8 and 6|9 respectively `which llie flushv against the free ends of the members 596vrand 591. The purpose of this arrangementuisto properly align the first .cracker C' vwhich has, been deposited on the conveyor chainsections, and immediately after it has had the lling F applied thereto so that when the second cracker 0 2 is fed onto the top thereof they will be in proper superposed relation. TheL description is for one of the mechanisms'associated with che of the five longitudinal sections of the-conveyor chain and like reference characters will apply as v`they are iden- Attentionlsespecially called t'o the flared out portions at 6I8 ,and 6|! in Figure 11i which serve to align the cakes in proper position immediately-beneaththedischarge openings of thell- Ving depositor 315. Also attention is vcalled to the fact that theseportions 6|8 and 6|0 in Figurel .project out over the edges of the cakes and there-k foreV holdthem down on the conveyor fand thus 4 prevent the lling while itis being deposited from dragging the cakes backwardly due lto the fact that the portions 6|3 and 6|9 willholdthe Acakes, C| down on the conveyor softhatthey will be carriedy along the conveyorrby the pins .immediately belowthe shortlegs if bell-ranks 605 and 606 is mounted a bar 622 Whichwis securedl at its-ends by thesame uprisers, 600 and 60|, which secure the transverse bar V602 at its ends. This bar 622 is ,used to slidably support the `short legs of the bell cranks 605 and 606 and thepins601. Y

, Transverse bar 51,-,has Aalready been described as supporting a plurality of vertically slidable members325 as is shown in Figures 8 and 1l. As has alreadynbeen describedkthe conveyorchain inthe present :invention has five rows ofv cracker supporting members |56 in addition to the means for properly .aligning theA crackers C| and. as has been described, ,it isl necessaryto properly align the top crackers C.2 after they have been deposited by the second cracker depositing mechanism. .1 v l ,Secured to the lower side of bar 51 and in the spaces between the points where the vertically movable members 32,5 are mountedare intermediate bars 630 (Figures 8 and 13) for the intermediate rows of crackersandwiches and outside bars 63|. The outside bars 63| and each of the intermediatebars 630 have oscillatably mounted therein vertically disposed pins 632 and `633. The upper ends of these pinshave fixed thereon levers 634 and 635 respectively.

The levers 634 and 635 are joined together by a, tension spring 636. Secured to the lower ends of pins 632 and 633 are guiding varies4 640 and 64|. The outside members 63| also have pins 632 and 633 as well as levers 634 and 0,35 and guiding vanes 64| thereon, their structure being identical to one side 'fof thestructure aillxed to themembers 630.

Y The members .640 .and 64| and server toproperly laterally align the top crackers C-2 which have been deposited on top of the filling material F, which has been discharged from the filling feeding apparatus 315. Thepins |65 which convey the crackers through the machine serve to align the top and bottom crackers longitudinally.

While the top and bottom crackers C-I and C-2 are being aligned transversely by the vanes 640 and 64|,l additional aligning means are provided to assist in this operation. Y t Disposed fon each side of each* longitudinal row of' sandwiches disposed on the conveyor belt mechanism is a pairl of angle bars 100 and 10| (Figures 5 and 7) which support the' finished sandwiches S for sliding movement and there yis disposed between these angle bars100and 10 |71; 'a bar 103 with suitable slots between the bar 103 yandV the angle bars 100 and 10|, for the pins. |65 to project into as theylift the finished sandwiches S onto the angle bars and 10|. y

It will be noted that the right-hand'`V end of these angle bars 100 and 10|, as well as the ,mide ,dle bar 103, slant downwardly so asto provide an inclined surface up which the'nished' s andwiches S may be moved bythe pins4 |65 before thepins |65 cease to be in engagement` withthe finished sandwiches S. These bars 1010 ,`10 rvand 103, are suitably supportedby thefa'ngle bracket Y14- previouslyV described. The sandwiches may move along these bars 100, 10| and |03 to a'suit- `able container or onto another conveyor. for further processing..Y u i A. y u y, The trackways |10 and |1| which support the are located. on opposed sides.. of the cracker supporting members ends of the transverse bars |66 and the pins therein, determine the elevation of the top ends of these pins as they progress through the machine, iy referring sto Figure 6,A one of the trackways. 11| .iS. there visible arid the other trak: wayk |10 is identicalon the other side of vthe machineV V(Figures 57,6 and v'1). y Thereitis'noted that the upward movement ofthe |65 'is begun and this elevation isnma'inta'ined until after theA pins |65 pass the rst cracker magasine. This causes thepins |65 to be raised up suffi? ciently ,to pass through thelslots 286 and 2'81 in the first set of cracker 'supporting members 215'.

After they havepassed .the first cracker receiving position, the trackways |10 and I1! ai'e. somewhat lower and occupy the positionshown in the right-hand portion of Figure '15 and this allows the top ends of the pins |65 to pass beneath the lling feeding apparatus 315, but will still be high enough to engage the rear edges of the first deposited crackers C -I to receive the filling F. After they have received the filling and have gradually started to rise as shown in Figure 6 and in the left-hand portion of Figurev l5 to where the pins |65 are elevated approximately to the position shown 'in Figure `8, they will pass through the slots or notches 'in the second cracker dispensing mechanism to engage the crackers C-2 disposed on the hori-l zontal platform formed by the flanges 284 and 205.v Then, after they have deposited the cracker C-2 on top of the filling F whiehhas been deposited on cracker C-I, they remain in this high position as shown in Figure '1 until they discharge their sandwiches onto the bars 100,10I and 103 and move downwardly from behind the rear edge of the finished sandwiches, thus, discharging the sandwiches from the machine. i i

YThe sandwiches discharged from the en ds of bars 10,0, 10| and 103 might be delivered to a suitable wrapping mechanism if desired, but in commonpractice, they are delivered onto a conveyor mechanism where operators on each side of an extended endless conveyor pick up al plurality of sandwiches and wrap them into a package ready for sale. I Y. In the event that the sandwiches `are disvcharged from the bars 100, 10| and 103 faster than desired and it is desired to cut down the capacity of the machine, then one or more of the discharge orifices of the filling feeding apparatus 315 can be closed. Before this is done. however, one of the gates 262 in one of the cracker feeding chutes 2|5 to 2|6 inclusive will be moved, in the'rst cracker feeding station, to closed position forthat line in the'conveyor in which the orifice is to be closed to 'stop the filling material. Then, of course, in the same line along the conveyor, lthe cracker dispensing gate 262 in the second cracker feeding magazine would be moved to closed position to thus entirely cut out one of the five rows of the conveyor from productive operation. Y l o In the' drawings and specification there has been set forth apreferred embodimentiof the invention, and although specific terms are em'- `ployed, they are used in ageneric and descriptive sense only, and not for purposes oflimitatiQn, the scope of the inventionl being defined in the claims.
